SPECIFICATION forming part of Iletters Patent No. 744,717, dated November 24, 1903. Application filed February 18,1903. Serial No. 143,977. (No model.)

To aZZ whom it may concern.-

Be it known that I, CHARLES A. CABLE, a citizen of'the United States, residing at J ohnstown, in the county of Oambria and State of Pennsylvania, have'invented certain new and useful Improvements in Window-scaffolds, of

which the following is a specification.

My invention relates tonovel improvements in window-scatfolds,'the object being to provide a simple, inexpensive, and efficient window-scaffold easily adapted to any window.

The invention consists in the construction,

novel combination, and arrangement of parts hereinafter more fully described.

In the accompanying drawings, Figure l is a perspective view of a window-'scalfoid constructed in accordance'with this invention. Fig. 2 is a central longitudinal section. Fig. 3 is a transverse sectional view. Fig. 4 is a top plan of one of the supporting parts. Fig. 5 is a side elevation shown folded.

Like numerals designate corresponding parts. i

1 designates a bar or brace, preferably of Wood, which fits inside the easement. 2 is a clamp to hold said bar or brace firmly on the window-sill.

3 designates longitudinal supporting-bars of any desired length, breadth, and thickness, the ends of which are bent around the bar or brace 1 and riveted at 4, as shown. A platform 5 is placed on top of said bars 3 and secured thereto by any suitable means. The ends or points of bars 3 project beyond the rivets 4 and are bent upward and outward sulficiently to leave a slight space between said ends and the platform. Under the platform 5 a rod 7 passes through cleats 8 and is secured by hand-nut 9 and eyebolt 10. Braces 11 are formed by yokes 12, fulcrumed on rod 7, as shown, the ends of said yokes being bent, as shown at 13, to rest against the wall, and a strip 14:, which is fulcrumed on said yokes 12 at-15, as shown, and notched, as shown at 16. Said notches engage with the rivets 17 between the perpendicularly-inclined and outwardly-turned ends or points of longitudinal supporting-bars 3 and pieces of metal 18, riveted to said points, asshown. By reason of the novel construction of braces 11 they can be folded beneath the platform 5 when not in use. When the scaffold is placed in position, said braces 11 can, by means of notches 16 and rivets 17, be adjusted so the platform will be level or inclined at any desired angle.

19is a handle attached to platform 5 for the more convenient handling thereof.

20 is a screen formed by the top rail 21, posts 22, wiring 23, and bottom rail 24 and held in place on the platform 5 by means of a button 25 and strips 26,said strips being preferably of light metal and fastened to the perpendicularly-inclined points of the longitudinal supporting-bars 3,.as shown at 27, and

having notches 28, which engage with a hook or pin attached to the screen, as shown at 29.

Having thus described my. said invention, what I claim as new, and desire to secure by Letters Patent, is'- In combination a window scafiold comprising a platform, longitudinal supporting-bars with the ends thereof bent around a bar fitting inside the easement, rivets holding said ends in place, points projecting beyond the rivets and turned upward and outward so as to leave a slight space between said projecting points and the platform, yokes fulcrumed on a rod beneath the platform, a notched strip fulcrumed on the yokes and engaging with rivets between the upwardly and out-- wardly' turned points and metallic pieces secured to said points, and a screen secured to said platform substantially as and for the purposes described.

In testimony whereof I affix my signature inpresence' of two witnesses.

CHARLES A. CABLE.
